THQ revealed a February 22, 2011 release date for de Blob 2 for Wii and DS.
The game, developed by Blue Tongue on Wii and HalfBrick on DS, continues the story of the lovable blob as he fights for the color revolution against the villainous Comrade Black. In the sequel, you will be able to jump with a button instead of a motion, which was an issue most gamers had with the first game in the series. It also adds co-op and more gameplay variety.
The DS version, which we covered during E3 2010, is a side-scrolling platformer in a similar vein as the recent portable Sonic the Hedgehog games.
The original game, released in 2008, was a Wii exclusive. There was a DS version planned, but it was never released.
